Research On The Optimization Strategy Of Liaocheng Canal Historical And Cultural Blocks From The Perspective Of Spatial Perception

The spatial formation,development and evolution of the Beijing-Hangzhou Canal historical and cultural block are all along with the opening,prosperity and decline of the Beijing-Hangzhou Canal,with distinct geographical characteristics and unique spatial texture,is an important part of the Beijing-Hangzhou Canal linear cultural heritage.Liaocheng Canal historical and cultural Block is a typical historical block along the Shandong section of the Beijing-Hangzhou Canal.Its spatial pattern is directly influenced by the shape of the Beijing-Hangzhou Canal,and it is the material carrier of the Beijing-Hangzhou Canal transport culture.In the past to liaocheng canal in the study of the historical and cultural blocks,research theory and the protection scheme to update the design block material,lack of mental subject and the object space correlation analysis,to improve the space image of the blocks in the observer’s perception of the level,there is block and canal tour activities of collaborative,poor neighborhood characteristics,distinct,patchy tour line status.These phenomena show that the spatial optimization of Liaocheng Canal historical and cultural block is in urgent need of new perspectives and ideas.This study from the perspective of space perception to observer the subjective perception and block space structure as the breakthrough point,the connection between the liaocheng from the macro,meso and micro canal space perception of present historical and cultural blocks,at all levels,then block space layer into the type of optimization strategy in order to enhance the quality awareness.The paper is divided into five parts:Chapter one is the introduction,which elaborates the research background,purpose and significance of the selected topic,defines the concepts related to the canal historical and cultural blocks and spatial perception,summarizes the research results at home and abroad,selects appropriate research methods to help construct the research framework and lists the research innovation points.The second chapter sorts out the development course of Beijing-Hangzhou Canal historical and cultural block and expounds its contemporary value significance,and analyzes the evolution of spatial pattern and functional layout of Liaocheng Canal historical and cultural block.Further research was carried out on the status quo of land use,street space and architectural style of the block,providing a research basis for the subsequent analysis of the perception quality of block space.The third chapter analyzes the current situation of Liaocheng canal historical and cultural block from the macro,meso and micro levels: at the macro level,it analyzes the change of the energy center transfer and the traffic accessibility at the urban level,and analyzes the correlation between the perceived intention of the block;At the meso level,the subjective perception of the streets and alleys is obtained through questionnaire survey,the spatial topology of the streets and alleys is analyzed,and the subjective perception and the space of the streets and alleys are analyzed cooperatively;At the micro level,the public space nodes are classified according to the morphological characteristics,and the typical nodes are selected as samples to analyze the relevance between the horizon characteristics and the spatial experience.The fourth chapter puts forward the progressive optimization strategy for Liaocheng Canal historical and cultural block: at the macro level,the linkage development with regional advantages breaks the closed development status of the block,continues the spatial texture of the canal historical and cultural block and integrates functional groups;At the middle level,the traffic flow lines of streets and lanes are sorted out and narrative logic is improved.Meanwhile,the harmony of spatial interface is optimized and the perceptual potential of characteristic streets and lanes is explored.To create a dynamic system of public space at the micro level,enrich the perception experience of point public space,connect the dynamic space of linear canal,and improve the aggregation effect of plane public space.The fifth chapter summarizes the results of this research,and puts forward the shortcomings of the research and further prospects.
